Specification of Letters Patent.

Patented Get. 1 Z, 1916.

Application filed February 19, 1915. Serial No. 9,331.

.l e it known that I, \Vxi/rin: l Merrily, a citizen of the lhiitedStates, residing at thicago, in the county of Cook and State ofIllinois, have invented certain new and useful improvements inPressed-Steel C-ar Ends, of which the following is a specilication.

y invention relates to an end structure for railway cars, particularlybox cars, and more especially to an end made up of plates or panels ofsheet metal pressed or otherwise formed with strengthening and rigidifving corrugations; and the principal object of the invention is toprovide a structure of this character comprising a plurality of superposed plates or panels formed with corrugations which extend at anangle to each other, one set preferably extending horizontally acrossthe end of the car from one corand the other corrugations extendingvertically from the end plate to the sill; said corrugatimisconstituting structurally crossed beams r arches giving the end strengthand rigidity to withstand external shocks, but more particularly thestresses, shocks and pressures from the inside of the car due toshifting cargoes.

The invention has for further objects such other new and improvedconstructions, arrangements and devices relating to sheet metal car endsas will be hereinafter dc scribed and claimed.

The invention is illustrated, in a preferred embodiment, in theaccompanying drawing wherein- Figure 1 is an end elevation of thesuperstructure of a railway box car provided with sheet metal corrugatedreinforced cnd constructed in accordance with my invention, and Fig. 2is a vertical sectional view taken on line 2-2 of Fig. 1.

Referring to the drawing, the end sill of the car is designated 10, theend plate 11, the roof 12, the flooring 13, and the corner posts 14.

The end structure, in the preferred embodiment shown, consists of threesheet metal plates or panels 15, 16, 17 formed with horizontalcorrugatirms 18, 18, and two plates or reinforcing members 19, 19.formed with corrugations 9.1: which extend vertically, the panels beingsuperposed upon the panels 15, 1G. 17 and secured thereto at intervalsby rivets 21/ The panels 15, 16, 17 have their edges overlapped andriyeted to gether by rivets 22. The upper panel is secured to the endplate 11 by bolts 23. The lower panel 17 is preferably formed with aninturned. flange 24. which intervenes between the flooring of the carand the end sill 10 and is suitably anchored to the latter. All threepanels 1?), 16, 17 are formed with angular flanges 25 which overlap andare secured to the corner posts 11. The panels 1!) are fastened to theend plate 11 by bolts 26. he attachment of the and structure to theframing of the car is prcferabty made more secure by means of gusscts 27and tie bolts 28.

The corrugations 18, 18*, project alternately outwardly and inwardly andterminate within the edges of the panels, the corrugations preferablymerging one directly into the other so that the center portion of thestructure consists of Li. series of horizontal beams or arches onedirectly above the other. The corrugations taper or merge into the flatmarginal portions.

The corrugati .)ns 2() are preferably deepest and widest atpoints belowthe center horizontal line of the end structure and taper graduallytoward their extremities. Thus beams or arches are provided which crossthe beams constituted by corrugations 18, 18, the thickest or deepestportions of which are in the lower portion of the end where the-cargothrusts are likely to he heaviest.

The upper panel 15 is preferably formed with a door opening 29 closed bya sheet metal door 30 held in place by a locking bar 31. The doorconstruction, however, is not claimed herein.

While 1 have described my invention in a preferred embodiment, it willbe understood that modifications might be made without departure fromthe principles of the invention. The number of panels alight 0bviouslybe varied for example. Therefore I do not wish to lie/understood aslimiting the invention to the precise constructions, ar-- rangcmcnts anddevices shown except so far as the claims are expressly so limited.
